Please stop sending patches to my Linaro mailbox, and use shawn...@kernel.org instead. You should already get that if you ever run ./scripts/get_maintainer.pl on the patch. Also please always copy ker...@pengutronix.de for i.MX platform patches like this. > --- > arch/arm/mach-imx/Kconfig | 1 + > arch/arm/mach-imx/Makefile | 2 + > arch/arm/mach-imx/common.h | 4 + > arch/arm/mach-imx/pm-imx7.c | 917 > +++++++++++++++++++++++++++++++++++++++ > arch/arm/mach-imx/suspend-imx7.S | 529 ++++++++++++++++++++++ > 5 files changed, 1453 insertions(+) 1453 lines addition to kernel only for i.MX7D suspend support. Yes, this is the way we support suspend on i.MX6, but that's enough, and we have to stop this somewhere. I would ask you to take Sudeep's comment and adopt PSCI for i.MX7D power management.
